A Novel Application of RNA In Situ Hybridization in the Analysis of Vitamin D Receptor Expression in Psoriatic Skin Tissue Following Etanercept Treatment.

ABSTRACT: Psoriasis is a chronic inflammatory skin disease marked by abnormal keratinocyte proliferation and immune dysregulation. The vitamin D receptor (VDR) plays a crucial role in regulating skin cell growth and immune responses, but its expression in psoriatic skin and modulation by treatment remain unclear. This study aimed to analyze VDR mRNA expression in psoriatic skin tissue before and after etanercept therapy using RNAscope, an RNA in situ hybridization technique that, to the best of our knowledge, has not previously been applied in psoriasis research. Two bio-naïve adult patients with moderate to severe plaque psoriasis received etanercept (50 mg weekly) for 12 weeks. Skin biopsies from lesional and perilesional areas were collected at baseline and post-treatment. VDR expression was asse
